This is a tool-assisted speedrun. For more information, see http://tasvideos.org/3726M.html. TAS originally published on 2018-06-12.
This game, aka. Probotector II Return of the Evil Forces, is, implicitly, Contra 2. The guys who have an infinite supply of ammo and who destroy worlds bare-chested are back!
In this run, Soig improves the predecessor movie (http://tasvideos.org/830M.html) by Baxter (http://tasvideos.org/Baxter.html) and adelikat (http://tasvideos.org/Adelikat.html) in 53.39 (3,204 Frames @60 FPS) seconds thanks to a bunch of new glitched found over the years, namely the glitch with the boss in Area 1, elevator glitch in Area 4, and the ceiling glitch in Area 8.
There is also a one-player run (http://tasvideos.org/3239M.html) of this game, as well as a pacifist version (http://tasvideos.org/2276M.html).
